Title: Multipurpose slope walking implement
Inventor: YUDA AKIO
IPC: A43C15/09
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a pair of multipurpose slope walking implements which solves the problems that snow shoes, clampers, etc., as walking devices to be mounted to the lower parts of mountaineering boots or work shoes in the case of walking on a surface covered with snow are not suitable for traversing a steep slope as the muscles of ankles, etc., are burdened due to the inclination of the mountaineering boots or work shoes at the same angle as the slope in the case of traversing a steep slope. SOLUTION: In this pair of multipurpose walking implements, by providing each cylindrical pipe between a main body frame to be in contact with a surface covered with snow and a shoe, it is possible to incline the shoes to the right and left. Only by strongly stepping on the shoes at the time of traversing a steep slope, it is possible to make the main body frames at the same angle as the slope and to make the shoes horizontal. Therefore, it is possible to traverse with the sense of walking on a level ground, and ankles, etc., are hardly burdened.

Filed: 1990-12-21
Abstract: PURPOSE: To obtain an alcohol in high selectivity useful as synthetic intermediate, for plant protective derivatives, by reacting an epoxide with a nucleophilic compound containing a labile hydrogen in the presence of a specific metal complex catalyst.  
     CONSTITUTION: An epoxide of formula I (R is an organic residue) is reacted with a compound of the formula ZH containing a labile hydrogen (e.g. an alcohol, a phenol, a primary amine or a carboxylic acid) in the presence of a catalyst to give an alcohol of formula II or III, wherein a metal complex of formula IV ((x) is 1 or 2; M is tin, lead or cadmium) is used as the catalyst to give an alcohol of formula III in high stereoselectivity. Use of the metal complex makes it possible to increase the yield and the selectivity for the opening of the epoxide ring as distinct from its isomerization to a carbonyl derivative and/or its polymerization. The metal complex is obtained by electroreduction of Co 2 (CO) 8  in an organic solvent medium in a cell in which the anode consists of the metal M, and the complex when (x) is 2 is novel.
